[reefwars]

what kind of tangs?

[hondas3000]

if things are dying like that then your water para is not right, double check again maybe your test kit is expire.

We're they doing alright for awhile or they new additions?

[Bayside Corals]

Bring in a water sample we will double check it for you. Your test kits might be off.

I have seen tangs eat corals before that is a possibility. You may also have a zoa eating pest like nudibranches or spiders.

But if other corals are not doing great either I would say a fish is eating them or its a water issue.

I'd bet on amphipods. Seen it happen 100 times. Take a look in your tank few hours after lights out. I bet you find the culprit.
